Least principal stress as function of depth in Gulf of Mexico (Matthew and Kelly)
Input(s)
\(S v\): Vertical Overburden Stress (psi)
\(K i\): Constant as Function of Depth (dimensionless)
Pp: Pore Pressure in Reservoir (psi)
Output(s)
\(\mathrm{S}_{\mathrm{hmin}}\): Minimum Principal Stress in Reservoir \((\mathrm{psi})\)
Formula(s)
\[
\mathrm{S}_{\mathrm{hmin}}=\mathrm{Ki} *(\mathrm{~Sv}-\mathrm{Pp})+\mathrm{Pp}
\]
